1 Claim.

The invention relates to a wheel for mounting on the shaft of a shoefinishing machine for the purpose of roughening leather or leather taps,welts and uppers on McKay shoes to remove all loose flesh on theleather, raise a nap and leave small grooves in which to apply leathercement for the purpose of cementing half soles, full soles, taps,leather pieces or the like in place, without the use of nails, wire orstitches.

The object of the invention is to provide an exceptionally simple andinexpensive wheel construction which forms a rigid unitary structurewhen applied and is readily applicable to a shaft without the necessityof stripping the latter of other wheels and the like and sliding theroughing wheel endwise thereon.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accom--plished by reference to the accompanying drawins.

Fig. 1 is a side elevation of the improved roughing wheel.

Fig. 2 is a vertical sectional view on line'2-2 of Fig. l. v v Fig. 3 isa vertical sectional View on the plane indicated by the line 3-3 of Fig.2.

Fig. 4 is a perspective view showing the two sections of the wheel swungoutwardly from engagement with each other.

A preferred construction has been illustrated and will be specificallydescribed, with the understanding however, that within the scope of theinvention as claimed, minor variations may be made.

In the drawing above brieflydescribed, the numeral. 5 denotes an innercollar which may well be formed of wood, said collar being composed oftwo semi-circular sections 5 and 5 Two outer collars 6, preferablyformed of metal,

are provided at opposite sides of the collar 5, in

co-axial relation with the latter, and while the inner peripheries ofthe three collars 5 and 6 are flush with each other, said collars 6 areof greater radial length than said collar 5, so that said collars 6project radially beyond the collar 5. By means of screws 8, the collarsections 6 are secured against opposite sides of the collar section 5and by means of screws 8 the collar section 6 are secured againstopposite sides of the collar section 5 The collar sections thus securedtogether, form two composite semi-circular wheel sections 9 and 9 and itwill be observed that the ends of said collar sections are offsetcircumferentially so that one end 5 of the collar section 5 projectsbeyond the corresponding ends of the collarsections 6 and the oppositeend 5 of said section 5 is inwardly spaced from the corresponding endsof said sections 6?. Similarly, one end 5 of the collar section 5projects beyond the corresponding endsof the collar sec- J tions 6 whilethe opposite end 5 of said collar Screws 10 are provided to secure theends of the collar sections 6 to the ends of the collar sec-y tions 6*,thereby holding the composite wheel sections 9 and 9 upon the shaft. Toovercome liability of the shaft turning within the wheel, set

screws 11 may be provided.-

A flexible band 12 lies against the outer periphery of the collar 5between the projecting edges '7 of the collars 6, the ends of said band,

being turned inwardly upon the ends 5 and 5 of the collar 5, and beingsecured by spurs 13 and 13*, carried by said collar ends. 12 carriesangular wire fingers 14 which perform the required rougheningof theleather or the like.

When the screws 10 are removed, the two wheel The band T sections 9 and9 may be moved apart as shown aration of the wheel sections 9 and 99also facilit itates removal of one band 12 and substitution of another..No claim is herein made to this band and its fingers 14, for thisfinger-equipped band may be purchased upon'the market.

It will be seen from the foregoing that a novel andadvantageousstructure has been provided for carrying out the object ofthe invention, and

while the details disclosed are preferred, attention is again invited tothe. fact that variations may be made within the scope of the inventionas claimed. 1 r
